Ofelia Mavroidis was a female Ullian Starfleet officer active in the late 24th century. By 2381, she served as a flight controller aboard the USS Aventine.

Mavroidis was on duty on the Bridge when the Aventine answered the distress call of the USS Enterprise-E in the Azure Nebula. She was also on duty when the Aventine began to scout the subspace tunnels in the nebula. During one such passage, the ship ended up in the Delta Quadrant and discovered a debris field of Borg wreckage and a strange alien who possessed the telepathic woman, speaking through her. It called itself the Children of the Storm and demanded that the Aventine depart or it would be destroyed. When Captain Ezri Dax agreed to the conditions, the alien released its hold over Ofelia.
